Question

If S.I. on a sum of money for 5 years, ¼ of the sum, the rate percent PA is​

Answer 1

Answer:

Suppose the sum = P

Then the Simple interest I = P/4

Time t = 5 years

If the rate of interest p.a. = r%

Then I = Ptr/100

=> P/4 = P × 5 × r/100

=> r = 100/20 = 5%

Answer 2

Let the principal be x

Then, simple interest=
